ABAQUS Tutorial, Rayleigh damping

[@seraioria]

Hi great video, Could you please explain how to find the modal damping coefficent for every natural frecuency on Abaqus? Thanks

[@KSSE_Engineer]

There are some simple equations in the Abaqus documentation plz have a look.

[@landrytim8595]

great video man!! could you make a videos about steel damage using abaqus subroutine umat

[@KSSE_Engineer]

You can do without UMAT , I will make a tutorial.

@@KSSE_Engineer ok sure kindly upload the link when done

[@susmitaghimire2964]

can you please tell what should be the unit of w to input in the given formula like it should be in radian or HZ. I am confused since the result of modal analysis is in HZ I think but not sure. So, should I convert the value of frequency from result of natural frequency or simply input the same value.

[@KSSE_Engineer]

Check it in Abacuse documentation there is unit consistency. For this work I used mm,ton,s so the natural frequency will be in Hz.

[@susmitaghimire2964]

@@KSSE_Engineer I am using m, Kg, sec and the result of natural frequency is in cycle/sec. So should I input the same value or convert it in radian for calculating alpha and beta.

great vidio, but what is the loading set in the "History output" ?

[@KSSE_Engineer]

You can make a set for loading.

Sir please make a video for cyclic performance of a corrugated steel plate shear wall with vertical, horizontal and inclined orientation of infill plates

[@KSSE_Engineer]

Ok noted

[@BirhanuDamesa]

given structural damping ratio in steel beam e.g damping ratio 0.5 and time period 10 sec how it is possible to analyse dynamically

[@KSSE_Engineer]

You can check.
